js 重组数据

Question

求助_(:3⌒ﾞ)_
现在后台返回的数据是这样的：selected=['FREQUENT_PURCHASE','HIGH_CONSUME','NO_COMMUNICATE','DRIVE_RECORDER','SMART_LOCK','CHILD_MACHINE','FACE_RECS'];但是我想要的是
selectd={
userTag:['FREQUENT_PURCHASE','HIGH_CONSUME'],
communicationIntention：'NO_COMMUNICATE',
products:['DRIVE_RECORDER','SMART_LOCK','CHILD_MACHINE'],
cloudServices:['FACE_RECS'],
}
怎么根据下面的数据去重组？？

像FREQUENT_PURCHASE这样的串，首先你要获取到它是data中的哪一类。可以遍历一遍data生成一个映射表typeMap：{CLOUD_STORE:'CLOUD_SERVICE',FACE_RECS:'CLOUD_SERVICE',CAMERA:'HAVE_PRODUCT',//...}你想要的selected，可以先初始化：lettargetSelected={userTag:[],communicationIntention:[],//...}这里有个小问题是targetSelected与data中的键不一致，但是一一对应，所以你要么写个函数，要么写个映射表,可以根据data中的key得到targetSelected中的key：functiongetKey(src){if(src=='CLOUD_SERVICE')return'cloudServices'//...}这样，对于后端返回的数组selected中的每一项，分发到targetSelected即可。selected.forEach(type=>{letkey=typeMap[type]targetSelected[getKey(src)].push(type)})其实很简单，但最好的方式后端直接返回规范的数据，如果实在不行再用上面的办法。
